Note: due to the issue noted in [Closures over types are type unstable](https://discourse.julialang.org/t/closures-over-types-are-type-unstable/82337), one must capture `T` using a `where`, rather than using `typeof`. The aforementioned issue addresses the case where this is not possible – I don’t have a solution in this case yet.
